Wilton Calderon, a 46-year-old who now lives in Old Lyme, Connecticut, appeared in Portage County Circuit Court and pleaded guilty to two counts of third-degree sexual assault and one count of manufacturing or delivering a non-narcotic drug.

Elizabeth Constable, a former assistant district attorney for Portage County, is prosecuting the case and agreed to recommend Calderon receive up to 12 years of initial confinement in prison. Timothy Verhoff, Calderon’s defense attorney, will be free to argue for any sentence as long as it includes prison time. Calderon will also be required to register as a sex offender as a result of his conviction.

Calderon was accused of groping and inappropriately rubbing himself against at least seven patients, according to a criminal complaint. Calderon worked as a doctor at the Ministry Medical Group Plover clinic at 2401 Plover Road before he left the organization in January 2015.

The investigation into Calderon began after police got an anonymous tip. The victims — all of them adult women — accused Calderon of sexually assaulting them during routine exams that took place between 2011 and 2014.

The maximum penalty for third-degree sexual assault is 10 years in prison and a $25,000 fine.
